Furthermore, why does bitter fury go with the sullen breed of lions, why craft with foxes, why is the instinct of flight transmitted to deer from their fathers, the father's timidity impelling their limbs, why are all other qualities of this sort generated in the body and the character from the beginnings of life, if not because in each seed and breed its own fixed power of mind grows along with each body? But if it were immortal, and accustomed to pass from body to body, living creatures would show confused habits: the dog of Hyrcanian breed would often flee before the horned stag's onset; the hawk would tremble, flying through the air from the advancing dove; men would lack reason, the wild generations of wild beasts would have it.
